The top political leadership in the government is believed to be upset with the alleged lackadaisical attitude of Bassi, an appointee of the previous UPA government, under whose watch the incidents have taken place in recent months.
Sources said the 1977 batch Union Territory cadre IPS officer has been conveyed by the top echelons of the government a fortnight ago to improve the law and order situation in the city.
Home Minister Rajnath Singh, who is on a tour of the Northeast, also spoke to the Police Commissioner and instructed him to conduct a speedy inquiry and find out the culprits responsible for the school attack.
Sources said action may be initiated against Bassi if he fails to stop attacks on minority establishments and improve the overall security situation in the national capital.
